UNITED STATES PATENT OFFICE.

JOHN CADY, OF STAFFORDVILLE, CONNECTICUT.

IMPROVEMENT IN PICKERS FoP. Looms.

To a/ZZ whom it may concern,.-

Beit known that I, J oHN CADY, of Staffordville, county of 'lolland, andState of Connecticut, have invented certain new and useful Improvementsin Shuttle Drivers or Pickers 5 and I do hereby declare that the same isdescribed and represented in the following speciication and drawings,and to enable others skilled in the art to make anduse the same, I willproceed to describe its construction by referring to the drawings, inwhich the same letters indicate like partsin each ot' the figures.

This improvement relates to a certain device designed to take the placeof common pickers, usually made of bualo-hide, for impelling the shuttlein looms for weaving fabrics, the nature of which Will be fullyunderstood from the accompanying specification and drawings, in which-Figure l is a side view of the :improvement attached to the upper end orsection of the picker-staff, which plays through openings in the bottomof the shuttle-box. Fig. 2 is atop view of the clamp portion of thedevice which holds it to the sta. Fig. 3 is a sectional face view cutthrough the line a, showing the ribs which hold the strips of leather(or other elastic material) in place, or to prevent a side- Wise motionthereof. i

A is the upper end or section of a pickerstaff, the lower end of whichis secured on each side of a loom-lathe, and is operated much in thesame way of operating the whiplever, the upper end of which playsthrough openings in the bottom ofthe shuttle box. B is a metallic claspfor holding the leathers (or other elastic substance) to receive theconcussion ofthe shuttle, and to impe] it forward in` its return motion.vo are ribs, which serve to hold the leathers, tc., in place. d areprojecting points to hold the clasp from moving up or down on the staff.(Shown by dotted lines in Fig. l.) Cis a metallic clamp, theforked endse of which are of such shape as to hook into the recess portion j' ofthe clasp B, and will be held in their proper position by the thicknessof the staff A. h is a set-screw arranged in the outer end of the clampC, having a ratchet-pad, i, secured on the inner end thereof. The objectof this pad t is to prevent a backward motion ofthe screw h when thepickers are secured to the staff thereof. These leathers may be quicklyand easily taken out, and replaced when desirable, the stock for whichmay be supplied from waste leather. By this improvement a more usefuland durable article is produced, and also one more easily removed andreplaced and adjusted.

I believe I have shown the nature, construction, and operation of myimprovement so as to enable a person skilled in the art to make and usethe same.

What l claim, therefore, and desire.. to secure by Letters Patent, is-

'lhe clasp B, clamp C, and leathers D, in combination with the staff A,for the purpose as described.
